ANDREW EINSFELD, OF SAN FRANCISCO, CALIFORNIA.

DUPLEX MOP.

Application filed June 29, 1916.

To all whom it may concern:

Be it known that I, ANoRnw EINsrnLn, a citizen of the United States, and a resident of the city and county of San Francis'co, State of California, have invented a new and useful Duplex Mop, of which the following is a specification.

My invention relates to mops and particularly to mops for oiling and polishing floors.

An object of my invention is to provide a mop holder and means for readily attaching the mop to or detaching it from the holder Another object of the invention is to provide an improved means for attaching a handle to the mop.

The invention possesses other features of advantage, some of which, with the foregoing, will be set, forth in the following description of the preferred form of my invention, which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claim.

Figure 1 is a perspective view of the mop of my invention, a portion being broken away.

Fig. 2 is a view of the tightening or tension band.

In mops of the class described, it is a matter of great importance to be able to easily remove or attach the mop to the mophead. In the mop of my invention I contemplate the use of two mops with each mophead, one for ap lying the olish to the floor and one for rubbing the door to a gloss. It is therefore one of the objects of my invention to provide a means for fastening the mops to the mopheadwhich is easily and quickly operated and which is absolutely secure and tight so that the mophead can never he accidentally loosened;

The mop of my invention comprises a mophead 2 formed conveniently of sheet metal and having its outer edges bent down wardly and curved to provide a rather broad grooved edge 3 around the periphery of the mophead. Preferably the mophead is triangular in form so as to permit of its ap-.

plication in corners.

Specification of Letters Patent.

Patented July 9, 1918.

Serial No. 106,604.

A mop 6 having an opening 7 lengthwise through its top edge 8 is adapted to encircle the mophead 2, the top edge 8 lying in the grooved edge 3 thereof. A band 9 is disposed in the opening 7 and surrounds the mophead and by tightening or loosening the band 9, the mop is bound tightly in the grooves or detached therefrom.

Preferably the band!) consists of wire links 12, 13 and 14 and the ends of the band are connected together by the turnbuckle 15. The middle link 13 is preferably bent in the center to conform to the shape of the mophead and the end links 12 and 14 are preferably attached to the middle link by means of eyes formed upon the ends of the links. Preferably the turnbuckle 15 is revolubly attached at one end to the link 12, and the other end of the turnbuckle is threaded to engage thethreaded end of the link 14:. A portion 16 of the edge 3 of the mophead is removed and the turnbuckle is preferably of a size such" that it extends closely adjacent this opening so that when loosening or tightening the turnbuckle, the fingers may easily engage the periphery thereof-on opposite sides. Preferably, also, the turnbuckle is provided with a hole 17 into which a nail or other small article may be inserted, so that, in need, a greater turning effort may berexerted upon the turnbuckle than would be possible by the fingers alone.

The top of the mophead is formed to provide two .wings or lugs 21 and pivotally mounted upon these lugs by means of the screw 22 is a socket 23 for the handle 24: of the device. The socket 23 is formed of stifl wire in' the form of a helix and the ends 25 are turned downwardly to form eyes through which the screw 22 passes. A spacing block 26 is mounted on the screw 22 between the ends 25 of the socket 23. The spacing block serves to position the ends of the socket relative to the wings 21. The end of the handle 24 is provided with threads 27 of the same pitch as the helical coil and is readily turned into or out of the socket formed by the coil. I

In attaching the mop to the mophead, the band 9 is passed through the opening 7 in the top edge of the mop and-both to ether placed upon the mophead, the top -e ge of the mop and the band lyin in the grooved edge 3. The turnbuckle 15 is then threaded applied to the 001' with one mop, then the mop changed and the floor rubbed to a gloss with the other mop. Bymerely unscrewing the turnbuckle 15 to loosen the tension band, the mop is easily slipped oif of or on to the mop head. Means ere-thus providedwherewith the change-fnom one mop to the other is efiected Withthe minimum of time and efiblfi'e I claim: 7 W 7 A11 article of manufacture comprising e mop, e mop heed having tabs cut from the theiecf turned ugiwerdi g form iugs thereon, a, helical ccii e3? ire have ing the ends formed into eyes adapted to lie contiguous with said lugs, e bio ck disposed between said eyes, a bolt passing through said lugs, eyes and block to pivotaily secure the coil upon the lugs, means forvsecuring the mop to the mo head and a handle provided with three s adapted to engage in said coil.

1ntestimon whereofl-I have hei'eunto set my hand at an Francisco, Celifornie,-this 3rd da of June, 191c.-
